&e.;of which the following is"a"s'pecilfication. a This invention relates to aniimprovemen t'in' that class'of feed devices which are applicax0 ble to grai'n-sc'ou're'rs', grain separators; grinda side elevation showing my improved feed '1 device applied to the shaking-screen ot-agrain scou'rer or separator. Fig.'2is a longi- .:5 -tndinal sectional elevation thereof. Fig. 31s

A represents the stationary frame of the grain scourer or separator, and B is the shaking screen or sieve, which is supported by ;5 flexible bars I) in the usual manner. The shaking-screen receives a vibrating motion from a horizontal shaft 0 by means of an cecentric D and a connecting-rod (l. E represents thcfeed-hopper, arranged ofabove the head of the shaking-screen B and "-jsecured to two-posts a' of the supporting- ;iframe A. The bottom of the hopper E is formed by two inclined stationary feedr boards 0 c. 5' F represents an adjustable feed-gate arranged below the stationary feed-board (a, and

whereby the throat of the hopper can be enlarged and contracted to regulate the feed. 1 The feed-gate F is mounted upon ahorlzontal I shaft-j", which is journaled in suitable bearin'gs arranged in the side walls? of the hopper'E.

Thefeed-gated and-oscillating. plate II ex-' tend-racross the entire width ot" the hopper, '75- ;an(l-' their lower ends form the t-ln'oatthereof. The plate I I issecured to a horizontal -rockshaft h, which is arranged in suitable bearings secured to the hopper K 3 I represents a rock-armsecu red to one end of the shaft h, and connected with its lower end to the shaking-screen B, so as to. be actuated by the same. The rock-arm I is provided at its lower end with a slot or fork 2',

which engages with a pin 11', secured to the p frame of the shaking-screen. A 5 represents plates or shieltlssecurcd.tothestationary boards a e',.and lapping over the feed-gate l. and oscillating feetl plate II, so as to cover thespaces between thcse'parts and prevent the material from escaping.through the said spaces.

The feed is regulated by adjusting thcgatc ll toward and from the oscillating plateby means of the screw and when'it is desired 5. to shut .oil' the 'l'eed entirely the motion of the screen is arrested and the l'eedgate-adjusted; so that'ils lower end rests against the lower end of the oscillating plate.

In the construction represented in Figs. i too and 5 my improved fee-d device is applied to aroller-mill.

ranged eccentrically upon; the journal and engaging in the slot of the rock-arm.

I claim as my invention V The combination, with a feed-hopper provided with inclined stationary feed-boards e e, of an adjustable feed-gate F, pivoted below the lower edge of the stationary feed-board e, a vertically-oscillating feed-board H, seou red to a horizontal rock-shaft f, arranged below The rock' the stationary feed-board e, the feetLgate i and feed-board l-I, facing each other and forming continuations of the stationary fCBLL boards 6 e', an adjusting-screw g, supporting the lower end of the feed-gate F, whereby the latter can be adjusted on its pivot; for contracting or enlarging the throatof the hopper, and an actuating-arm I, secured to one end of the rock-shaft; f, for imparting" to the feed-board II a verLically-oscillating movement, substantially as set forth.
